SOOT-CLEANER FGRWATER-TUBE BOILERS.

new.

Be it known that I, JOHN MAGEE, a citizen of the United States of America, residing at Detroit, in the county of Wayne'and State of Michigan, have invented certain new and usefullmpro'vements in Soot-Cleaners for Water-Tube Boilers, of which the following is a specification, reference being had therein to the accompanying'drawings.

This invention relates to soot-cleaners for water tube boilers and to an arrangement .f Referrmg-to the drawings, a lower drum '1and""u'pperddrum 2, mounted in a suitable" thereof that is'particularly adapted for a type of upright water tube boilers in one section of which, a lower main drum and an uppermain drum are connected by water tubes that are substantially upright and are arranged in sets that are separated by bafiies so that the gases of combustion from a fire or furnace chamber at one side of the setting which surrounds the boiler, pass longitudinally up and down and along the water tubes and final-1y escape from a smoke opening at the upper side removed from the gas inlet.

The invention includes means not only for cleaning .the tubes which are-in the hotter spaces of the boiler by means that can be readily withdrawn out of the action of the.

In' the'drawings, Figure-1 is'a view'in upright;longitudinal section of a boiler of the type hereinbefore described, equipped with-a blowerthat embodies features of the invention; Fig. 2 is 'a-view'in detail showing a blower unit adaptable for the hotter portions or passes of the boiler; Figs. 3 and l are detaillviews showing a blower support clamp.

are substantially straight and by outer sets 5 and 6, the end portions 7 and 8 of the latter being inturned so as to tap readily into the shells of the drums 1 and 2. A baiile '9, of suitable construction, such 'as'tiling or the like, extends from the lower drum up and along the set 6, the interyalbetween the top of the baflle and the upper drum 2 forming an inlet into a central down pass in which the .middle set 4 of the tubes is located, a baiile 10 extending from the upper drum 2 toward the lower drum 1 fornr ing the other Wall of this pass. The latter baiile also serves as a division wall between thereof and the gases of combustion enter through the throat or gas inlet indicated Patented Nov. 16, 1915.

at 12. As the lower portion has the pass in Y which the set 6 of tubes. is extremely hot especially toward the lower portion thereof, a removable blower unit is used. In preferred form this consists of a jet pipe 14 rotatably .mounted in a fitting 15 so as to be turned by a suitably connected handle 16 whereby jets may be rojected from suitable nipples oropenings 1 and end jettingholes 18 between and along the tubes 6. Arms maintained in a plane transverse to the tube 6 is thrust between them, Preferably the parts 17 are Venturi because of the increased efiect obtained by'the use of a Venturi bore in the nozzles. A stem pipe or supply line 19 is connected by a suitable swivel with anupright T 20 having an extension pivot rod 21 that together 'with the member 25 is journaled on a suitable base plate 22 as in brackets 23 or the like. A horizontal arm 24' from the fitting 20, the outer end of which is braced by a suitable diagonal member 25 carries an upright stem 26 on its outer end on which is swiveled a coupling member 27that in turn is connected by an elbow 28 and rotatable coupling indicated generally at 29 to the T 15. A valve 30 maybe inserted in the arm if desired. The base plate is mounted across a suitable opening in the furnace setting and. the .arm 14 is thereby swung readily in and out of position and manipulated by its handle so as to direct it in any desired way across arid along thetubes and over the interior smolzesurfaces',

A housing '82 is in'serted in a suitable opening of the setting 3 f the boiler to form a journal support for a jet pipe 33 that ex tendsthrough the setting and across the first tube and into the third pass of the boiler.

)Of course it may beextended entirely across tl1B like provide means for conveniently ro- 'tating the unit." I

the outer end by suitable fittings or hangers indicatedat 12', which are clamped or other and be supported at the other end in the setting if it is so desired. Suitable jet nozzles 34 on this pipe 33 are arranged to directjets between the water tubes of the sets in the p passes and against the interior smoke surfaces of the boiler. Steam is supplied to the pipe through a suitable fitting 35 that also forms, a bracket supp rt.- A. hand wheel or sprocket Wheel 36 and depending chain 37 or Another rotatable unit- 38 is likewise inserted in:jthe lower portion of themiddle and smoke passes in'a suitable bearing mem- 'ber 39 'with steam bracket connections 40 and manipulating wheel/l1. As the unit is directly opposite the-portionfof the boiler.

that is taken care of by' the retractable jet pipe 14, it does not extend into this passbut terminates in the middle pass.- Both the upper blowerunit 33 and the lower onej38 may be'supported along their length and at wise suitably secured to the water tubes of the boiler. Such clamps prefegqably consist each of a bearing bar 43 bridgihg a pair of tubes to which clips 44: secure them with an applied cap 45 embracing the jet pipe and. forming a closed bearing therefor. Both the rotatable blowers may be water or air jacketed or otherwise shielded as by an asbestos lined casing from the'eflect of the gases that .pass by them.

" As a result of this construction a blower is obtained that isparticularly adaptable for this type of boiler as it sweeps-and cleans all the water tube surfaces and the interior surfaces of the boiler that are in contact with I the gases of combustion and are liable to be coated with depositstherefrom. By'the use of the retractable member-'which is readilv accessible and accordingly easily 'manipulated, the extremely heated portions of-the passes are as readily reached as the more accessible and cooler ones.- The use of a hand blower is done away with a d the boiler is readily kept in order by operation of the blower without withdrawing the boiler from service. Obviously the particular distribution of the baffles and pipes of the boilers maybe other than as indicated in the drawings and in such case the blower units are necessarily varied to meet conditions of service.

Obviously, changes inthe details of construction may be made without departing from the spirit of my invention and I do not care to limit myself to anyfparticular form or arrangementof parts.

I \Vhat I claim is I 1. The combination of a b iler having up right water tubes, divided by bafiies whereby the tube space has substantially .upright passes through which the gases of combustion pass in opposite direction, with a blower comprising rotatable jetting means certain of which are common to all of the passes and others to some of the passes onlyand all of which are adapted to direct jets over and along the water tubes and against the interior, surfaces of the passes occupied by the tubes, and rotatable jettingmeans adapted to be projectedandretracted out of certain of the tube spaces and to direct cleaning jets along "the tubes and between them and in and along the interior'surfaces of the pass into which the means is moved.

2. The combination of a boiler having upriglitjwater tubes arranged in a setting and bafiies dividing the tube space into passes with ga'sinlet at the lower endof one pair whereby thegases of combustion are led over the tubes in the direction of lengththereof, a blower comprising rotatable jet tubes mounted inthe settingat intervals from the inlet and extended across the passes for directing jets over and alongthe tubes and the interior surfaces of the passes, means exterior to the setting for manipulating the tubes, and a bodily retractable and projectable jetting pipe mounted on the exterior of the. setting andadapted to be moved into operative relationtothe boiler tubesin the pass adj acentithe gas inlet for directing jets across and along them and'over the interiorsurfacesof the pass. a

3. In a boiler, upright-water tubes, a setting incasing the tubes, baflies dividing the tube space into. passes whereby the gases of combustion are led up and down the tubes in the'direction of length thereof; from a gas inlet at the lower end of one pass to a'smoke outletat the upper endof the last pass,a blower comprising a rotatable jet pipe rota-' tably mounted in the setting and on the water tubes acrosswhich it extends transversely through. the baflies into all of the passes at a considerable interval above the gas inlet, a jet pipe journaled in the setting and on the water tubes across which it ex-v along'and across the tubes and the interior surfaces of the passes, means for manipulatmg the jet pipe, a et pipe common to some of the passes at a distance farther from-the gas inlet, means rotatably mounting the pipe on the water tubes transversely thereto for directing jets of steam across and along the pipes and interior surfaces of the passes, means for manipulating the jet pipe, a supply line, a jet pipe, and swiveled connections articulating the jet pipe with the supply line, the jet pipe being thereby bodily movable into operative relation with the water tubes in the first pass, and means for rotating the jet pipe for directing jets across and along the Water tubes of the pass and interior surfaces of the latter.

5. 111 a boiler having water tubes and bafrles dividing the tube space into passes, a jet pipe for directing jets along and across the tubes in the interior surfaces of the passes, provided with jet-forming members of Venturi bore. 1

6. The combination With a boiler having upper and lower members connected by sets of substantially upright water tubes, baffles between the sets forming passes for conducting the gases of combustion along the water tubes in the direction of length thereof, and a setting'inclosing the tube space having a gas inlet into the first pass and a gas outlet from the upper end of the last pass of rotatable jet pipes secured in openings through the setting and baflies acrossthe water tubes, certain of the pipes being common to all of the passes at points remote from the gas inlet, means for rotatably mounting the pipes in position in the setting and on the water tubes, an articulated supply pipe connection mounted on the exterior of the setting and a jet pipe rotatably secured thereto and adapted to be moved bodily across the first pass above the-gas inlet and adjacent thereto intopperative relation with the water tubes ahd interior surfaces thereof, together witli means for rotating and controlling the latter jet 1 e. p in testimony whereof I afi'ix my signature in presence of two witnesses.
